To all whom it ma concern: 1

Be it k.own t at we, JEAN PAUL and Tni'iornrnn DUooUsso, citizens of.France, re-

siding at Paris, France, have invented new and useful Improvements in Systemsof Elec- -trically-Controlled Signals for Railways,

(for which we have tained a patent in France, No. 365,206, hearing date April 13,

1.906,) of which the following is a specification;

This invention relates to an improved system of signals for railways, the said system being controlled electrically.

.'.l'he invention consists of the features of construction and the combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

The invention s. illustrated in the accomjpanylng drawin s, in which:

Figure 1 is a ront elevation Fig. 2 a side elevation, and Fi 3 a plan view.

- The invention Includes a transparent casing 1, made of any suitable material, such as glass reinforced with wire, with a metallic brace 2. In located the movable signal which is composed of the two semi-circular portions and 6. p

4 indicates the support for the casing. One part of the signal is provided with a colored glass 7, behind which is placed the sists of a semi-circular support, 8, 9, fixed on a shaft '10, 11, and on which is fixed a sheet of suitable material. The ends-of the shafts 10, 11 are disposed. on pivot 12, 1'3, fixed to the casin 1 or to the brace 2 of the same, and are inclined slightly tolt-hevertical, as shown in Figs. 1 and 2, whereby said parts will, by the action of gravity, assume the positio. shown in Fig. 1, that is, they will lie against the bottom 3 of the casing, and the signal will be set.

When the way is clear and the signal is to be set so as not to be seen by the engineer, the parts 5 and 6 are turned in the direction of the arrows f in Fig. 3 until the assume the position shown in Fig. 2. The e ort necessary for producing said motion is furnished by an electro-ma met 14, whose armature is'connected throug 1' a suitable transmission 15, to a disk 16, fixedeccentrically on each one of the shafts.

and provided sald casing is Each part 5, 6 con- The.

displacement of the armature by the action of the electrical current, gives thus a tIa'CtIOD' 'efi'orton said eccentric i controll'e electrical y, by means of the weak current furnished by a primary pile.

It is further evident that the system of signal forming the object of the present invention is a p ical to the various forms of signals use in railways, the forms of the signal and cf the casing being varied according to each a plicatlon.

Having thus dzascribed and ascertained the nature of our invention, we declare that what we claim is:

1. An im roved system of signal electrically contro led for railways, comprising a transparent casing fixed on a suitable sup port, a movable signal in the said casing, the said signal consisting of two similar parts, two shafts by which said arts are pivotally mounted, disks eccentrical y mounted on said shafts, an electro-magnet, an armature, connection from the armature to the disks, and means whereby the signal will be set automatically by the action of gravity.

2. An im )roved system of signal electric ally control ied for railways, comprising a transparent casing fixed on a suitable support, a movable signal in the said casing, the said, signal consisting of two similar parts, shafts by which said parts are pivotally mounted, each one of said shafts'being slightly inclined in the vertical direc' tion, a disk eccentrically mounted on each shaft, an electric magnet, an armature, connections from the armatureto the disks for bringing the two parts of the signal together when the magnet is energized, said parts being returned to set position by the -action of gravity.
